3-Benzyloxy-phenylboronic acid → HCID 23062364, compound

Participants

Reaction Steps

A reaction and treatment was carried out in the same manner as in Reference Example 5(1) using ethyl 3,4-dibromo-2-furancarboxylate (2.00 g) and 3-benzyloxyphenylboronic acid (1.80 g). The residue was purified by silica gel column chromatography (eluent: ethyl acetate/hexane=1/20), thereby giving 1.70 g of a mixture of ethyl 3-(3-benzyloxyphenyl)-4-bromo-2-furancarboxylate and ethyl 4-(3-benzyloxyphenyl)-3-bromo-2-furancarboxylate and 0.26 g of ethyl 3,4-bis(3-benzyloxyphenyl)-2-furancarboxylate.
